6.  The applicants are:
(1) Mr Kursolt Bibolovich Dolsayev[1], born in 1949;
(2) Ms Mak (also spelled as Makka) Isayevna Dolsayeva, born in 1953;
(3) Ms Madina Kursoltovna Dolsayeva, born in 1982;
(4) Mr Shamil (also known as Adam) Kursoltovich Dolsayev, born in 1984; and
(5) Mr Baysongur Kursoltovich Dolsayev, born in 1995.
The first, third, fourth and fifth applicants live in the village of Martan-Chu, in the Urus-Martan district of Chechnya. Prior to her death in June 2007 the second applicant also lived there.
7.  The facts of the case, as submitted by the parties, may be summarised as follows.
8.  The first and second applicants were married. They were the parents of Beslan Kursoltovich Dolsayev, born in 1974, Mr Rizvan Kursoltovich Dolsayev, born in 1977, Mr Rizavdi Kursoltovich Dolsayev, born in 1978, and Mr Shuddi Kursoltovich Dolsayev, born in 1980, as well as the third, fourth and the fifth applicants.
9.  At the material time Beslan Dolsayev worked as a police officer of the department of the interior of the Zavodskoy district of Grozny (“the Zavodskoy ROVD”) and had a service machine gun. The Dolsayev brothers had positive references from local authorities and were not suspected of participation in illegal armed groups.
10.  From December 1999 Martan-Chu was under the full control of the Russian federal forces. From the end of September 2001 the village was under curfew from 8 p.m. to 6 a.m. The checkpoints of the Russian military forces were located on the roads leading to and from the settlement. Military servicemen conducted regular identity checks in the village; prior to the events in question they had visited the applicants' house for identity checks on eleven occasions.
11. On the night between 20 and 21 October 2002 Beslan, Rizvan, Rizavdi and Shuddi Dolsayev, the applicants and other members of the Dolsayev family were sleeping in their house at 4 Tsentralnaya Street, Martan-Chu, in the Urus-Martan district of Chechnya. At about 4 a.m. around thirty men in camouflage uniform and masks and armed with machine guns entered the Dolsayevs' yard. They were equipped with portable radio transmitters but used gestures to communicate among themselves. The men shouted that they belonged to the Main Intelligence Department of the Ministry of Defence (“the GRU”) and ordered everyone not to move. Ten of them broke into the house. Meanwhile, one or two armoured personnel carriers (“APCs”) and a Ural vehicle arrived at the house; their registration numbers were painted over.
12.  The servicemen ordered the men from the Dolsayev family to stand along the wall, checked everyone's identity papers and took Beslan Dolsayev's service gun. Some of them searched the house without producing any warrant and took away a large knife with a black handle.
13.  The servicemen then instructed Beslan, Rizvan, Rizavdi and Shuddi Dolsayev to go outside; the brothers were not allowed to put on clothing. After that, the four brothers were placed in the APC. The servicemen also intended to take the fourth applicant with them, but the second applicant dissuaded them from doing so as he was sick.
14.  Having locked the women together with the fifth applicant in one room and the first and fourth applicants in another, the intruders left the house and drove away in the APCs and the Ural vehicle.
15.  The applicants' neighbour Ms A.M. submitted in her witness statement that on the night of the abduction of the Dolsayev brothers she had been awoken by the sounds of heavy military vehicles passing by her yard. When she had looked out of the window, she had seen an armoured military vehicle on wheels. She could not identify whether this was a tank or an APC. The vehicle had been parked about 50 metres away, next to the school yard; its headlights were off, but it was clearly visible in the electric light coming from the school's boiler room. Some time later she had seen men in military uniform; the men had got into the vehicle and left without turning the headlights on. They had left in the direction of the military checkpoint located on the road to Urus-Martan.
16.  After the abductors had left, the first and fourth applicants were released from the room by their neighbour, Mr A.S. The first applicant ran outside and saw footprints in the yard and the vegetable garden. The footprints led in the direction of the school, located 40-45 metres away from the applicants' house. The first applicant followed the traces. Next to the school he saw APC tyre marks; they led in the direction of the road from Martan-Chu to Urus-Martan, where a military checkpoint manned by servicemen of the district military commander's office was located.
17.  The applicants have had no news of Beslan, Rizvan, Rizavdi and Shuddi Dolsayev since 21 October 2002.
(b)  Subsequent events
18.  On one of the days between the end of October 2002 and the end of November 2002, in the morning, the second and fourth applicants were together at a market in Urus-Martan. There they saw a Russian soldier holding the knife which had been taken away by the abductors of their relatives. The applicants recognised the knife by its shape and the black handle. They followed the soldier to the town's central square. There they met the first applicant and told him about the soldier. The latter was standing next to a group of parked APCs and military Ural vehicles. At that moment the first applicant saw an acquaintance of his who was a police officer, Captain T.Sh. The first applicant told him about his sons' abduction and asked whether he could arrest the soldier. Mr T.Sh. told the applicant that the police did not have the jurisdiction to arrest military personnel.
19.  According to the second applicant, in August 2003 she provided this information to the authorities investigating her sons' abduction. She did not mention to them that she had been together with her younger son when she had seen the soldier as she feared for her son's safety. The first applicant also provided the investigators with a statement concerning the events in question.
20.  In support of their application the applicants submitted a number of documents, including the following: witness statements provided by the first applicant on 20 May 2003, 13 July 2003 and on an unspecified date; witness statements provided by the second applicant on 20 May 2003 and on an unspecified date; a witness statement by the applicants' neighbour Mr S.A., provided on an unspecified date; a witness statement by the applicants' neighbour Mr A.S., provided on an unspecified date; a witness statement by the applicants' relative Ms Z.G., provided on 20 May 2003; four character references for Beslan Dolsayev, provided by the Zavodskoy ROVD, the Urus-Martan ROVD and the Martan-Chu village administration on 25 July 2002 and on unspecified dates; a copy of the newspaper announcement introducing a curfew in the Urus-Martan district as of 25 September 2001; four statements certifying that Beslan, Rizvan, Rizavdi and Shuddi Dolsayev did not participate in military clashes in Chechnya, all dated 22 May 2003; character references for Rizvan, Rizavdi and Shuddi Dolsayev, all undated; three hand-drawn maps of the premises of the applicants' house; and copies of documents received by the applicants from the investigating authorities.
21.  The Government did not challenge most of the facts as submitted by the applicants. According to the Government, “at about 4 a.m. on 21 October 2002 unidentified persons armed with automatic weapons arrived at the village of Martan-Chu in the Urus-Martan district of Chechnya and took Beslan, Rizvan, Rizavdi and Shuddi Dolsayev away from their house”.
22.  At the same time the Government contended that the applicants' statement of facts was unreliable. In particular, they pointed out that according to the first applicant's witness statement of 2 November 2002, the abductors had locked him in a room with his younger son Adam. However, several years later the applicant changed his testimony. In his witness statement provided on 16 May 2007 the applicant stated that he had been locked by the abductors in a room with his son Shamil and that he had heard one of the intruders saying to the others in Russian: “The commander said to leave Shamil [here] as he is an invalid”.
23.  The Government further pointed out that the applicants had not been sure about the precise number of intruders who had broken into their house on 21 October 2002 as in their statements the number varied from 10 to 25. In addition, the applicants had been inconsistent in their descriptions of the abductors' behaviour: the first applicant had stated that the intruders had initially enquired whether there were any weapons in the house, whereas according to the second applicant, the intruders had not asked any questions.
24.  The Government also expressed their doubts concerning the reliability of the witness statement provided by the applicants' neighbour Ms A.M. In particular, they questioned her inability to distinguish between a tank and an APC and emphasised that she had not witnessed the Dolsayev brothers being placed in the vehicles.
(b)  Subsequent events
25.  The Government did not dispute that the applicants had seen the soldier with the knife which had been taken away by the abductors. However, they contended that the first and second applicants had provided inconsistent accounts of these events: according to the second applicant's witness statement of 14 August 2003, the events in question had taken place about a week after the abduction and the soldier had been walking alone, whereas according to the first applicant's witness statement given at a later date (the Government did not specify the date), the events in question had taken place about a month after the abduction and the soldier had been accompanied by two other servicemen.
26.  The Government further stated that the applicants' failure to submit this information to the authorities in a timely manner had impeded the investigation into the abduction of the Dolsayev brothers.
27.  Since 21 October 2002 the applicants have repeatedly applied in person and in writing to various public bodies. They have been supported in their efforts by the SRJI. In their letters to the authorities the applicants referred to their relatives' abduction and asked for assistance and details of the investigation. Mostly these enquiries have remained unanswered, or purely formal replies have been given in which the applicants' requests have been forwarded to various prosecutors' offices. The applicants submitted to the Court some of their letters to the authorities and their replies. These documents are summarised below.
28.  On 21 October 2002, immediately after the detention of her sons, the second applicant wrote to the prosecutor's office of the Urus-Martan district (“the district prosecutor's office”) describing in detail the circumstances of their abduction and asking for assistance in releasing them. In particular, she pointed out that on the morning after the abduction she and members of her family had discovered APC tyre marks next to their family's vegetable garden.
29.  On 30 October 2002 the district prosecutor's office instituted an investigation into the disappearance of Beslan, Rizvan, Rizavdi and Shuddi Dolsayev under Article 126 § 2 (aggravated kidnapping) of the Russian Criminal Code. The case was assigned no. 61144. No investigative measures, other than the questioning of the first and second applicants on 2 November 2002, were taken following the opening of the criminal proceedings.
30.  On 22 November 2002 the second applicant wrote to the military commander of the Urus-Martan district (“the district military commander”), the Urus-Martan district department of the interior (ROVD) and the district prosecutor's office. She stated that her four sons had been abducted by servicemen of law-enforcement agencies of the Urus-Martan district and requested assistance in establishing her sons' whereabouts.
31.  On 11 December 2002 the military prosecutor's office of the North-Caucasus military circuit informed the second applicant that her complaint had been forwarded to the military prosecutor's office of the United Group Alignment (“the UGA”).
32.  On 30 December 2002 the district prosecutor's office granted the second applicant victim status in criminal proceedings concerning the kidnapping of the Dolsayev brothers (case no. 61144).
33.  On the same date the district prosecutor's office suspended the investigation in case no. 61144 owing to the failure to identify the culprits. On 16 January 2003 the district prosecutor's office informed the second applicant of the suspension of the investigation.
34.  On 24 January 2003 the Chechnya prosecutor's office informed the second applicant that in spite of the suspension of the investigation in criminal case no. 61144, operational-search measures were being taken to solve the crime.
35.  On 1 February 2003 the military prosecutor's office of military unit no. 20102 (“the unit military prosecutor's office”) informed the second applicant that it did not have any information either about the involvement of military personnel, the police or the Federal Security Service (FSB) in the kidnapping of her relatives or about the whereabouts of the Dolsayev brothers.
36.  On 3 March 2003 the Zavodskoy ROVD carried out an internal inquiry into the disappearance of Beslan Dolsayev. It was established that he had been kidnapped by “unidentified persons armed with machine guns and wearing camouflage uniform and masks”. Beslan Dolsayev's service machine gun was declared lost and put on a missing list.
37.  On 17 March 2003 the office of the Prosecutor General sent a report to the Commission of the Russian State Duma for Assistance in Political Settlement and Protection of Human Rights in Chechnya. The report provided data on disappearances in Chechnya and described investigative measures taken by the authorities to solve the kidnappings. The document referred to a specific group of disappearance cases, including the abduction of the Dolsayev brothers, in which the investigation had been opened and then suspended owing to the failure to identify the perpetrators. It noted that in all such cases the investigation had found no evidence implicating federal servicemen and that further steps were being taken to solve these crimes.
38.  On 24 March 2003 the Prosecutor General's office forwarded a letter from a deputy of the Russian State Duma accompanying the second applicant's complaint to the Chechnya prosecutor's office.
39.  On 4 April 2003 the first applicant requested the district prosecutor's office to inform him of the progress in the investigation into his sons' disappearance and to grant him victim status in the criminal case. On 11 April 2003 the district prosecutor's office replied that the investigation had been suspended on 30 December 2002.
40.  On 21 April 2003 the Chechnya prosecutor's office informed the second applicant that the time-limit of the investigation in case no. 61144 had been extended until 20 May 2003 and that it was supervising the criminal proceedings.
41.  On 25 April 2003 the district prosecutor's office informed the first applicant that it was not necessary to grant him victim status in the criminal case since his wife had already been granted such status.
42.  On 8 May 2003 the Main Military Prosecutor's Office forwarded the first applicant's complaint to the military prosecutor's office of the UGA.
43.  On 20 May 2003 the district prosecutor's office suspended the investigation owing to the failure to identify the perpetrators and informed the second applicant of this.
44.  On 13 June 2003 the Chechnya Ministry of the Interior (“the Chechnya MVD”) forwarded the first applicant's complaint to the ROVD.
45.  On 30 June 2003 the district military commander informed the second applicant that he had no information either about the whereabouts of the Dolsayev brothers or about the reasons for their abduction.
46.  On 11 July 2003 the military prosecutor's office of the UGA requested the unit military prosecutor's office to establish whether military personnel had been involved in the Dolsayev brothers' abduction.
47.  On 14 July 2003 the office of the Prosecutor General informed the first applicant that his complaint about the alleged ineffectiveness of the investigation in case no. 61144 had been forwarded to the Chechnya prosecutor's office.
48.  On 23 July 2003 the second applicant requested the Chechnya prosecutor's office to overturn the decision to suspend the investigation into her sons' abduction and to ensure that the investigators took the necessary measures to solve the crime.
49.  On 7 August 2003 the Chechnya MVD informed the first applicant that the identities of the perpetrators of the Dolsayev brothers' abduction had not been established, but that measures to identify the culprits were in progress.
50.  On 14 August 2003 the second applicant was questioned by the investigators. In her statement she pointed out that at some time between the end of October and the end of November 2002, in Urus-Martan, she had seen a soldier with the knife which had been taken away from her house by her sons' abductors.
51.  On 6 September 2003 the district prosecutor's office informed the second applicant that the investigation into her sons' abduction had been suspended on 6 September 2003.
52.  On 17 September 2003 the second applicant complained to the district prosecutor about the suspension of the investigation in the criminal case and requested that it be resumed. She expressed the opinion that her sons had been abducted by State representatives and pointed out that she had provided the investigators with detailed information which could have assisted them in identifying the perpetrators. In particular, she stated that she had told the investigators that the abductors had used military vehicles and had been able to pass through the checkpoints of the Russian military forces at night; that the abductors must have had permission from the military commander's office to drive through the checkpoints; that the investigators had failed to question chief officers of local law-enforcement agencies who could have given such permission; and that the investigators had demonstrated their negligent attitude towards the investigation by failing to preserve and examine the tyre marks found next to the applicants' yard and to question the servicemen who had manned the village checkpoints on the night of the abduction. The second applicant did not receive any response to this complaint.
53.  On 28 April 2004 the district prosecutor's office informed the first applicant that it was taking investigative measures to identify the perpetrators.
54.  On 17 October 2005 the applicants' representative, the SRJI, wrote to the district prosecutor's office requesting information about the progress of the investigation in the criminal case and asking for the applicants to be allowed to study the material in the case file. No response was given to this letter.
55.  On 16 November 2005 the first applicant wrote to the district prosecutor's office. He expressed the opinion that his sons had been abducted by representatives of federal forces. He complained about the ineffectiveness of the investigation and pointed out that the lack of information about the investigation precluded him from appealing against the investigators' decisions. He requested that the investigation into his sons' abduction be resumed and that he be allowed to study the investigation file. No response was given to this request.
56.  On 24 November 2006 the second applicant wrote to the district prosecutor's office. She requested that the investigation be resumed and that she be provided with information concerning its progress.
57.  On 27 November 2006 the district prosecutor's office informed the second applicant that it had rejected her request of 24 November 2006.
58.  On 28 November 2006 the district prosecutor's office informed the second applicant that on the same date it had suspended the investigation owing to the failure to identify the perpetrators.
59.  On 19 March 2007 the first applicant wrote to the district prosecutor's office. He complained about the lack of information concerning the investigation and requested that the investigation be resumed and that he be allowed to study the case file.
60.  On 22 March 2007 the district prosecutor's office informed the first applicant that “as a person who has witness status in the criminal case, [he did] not have the right to lodge the request [to study the case file]...”.
61.  On 10 May 2007 the first applicant complained to the district prosecutor's office about the lack of information concerning the investigation and requested to be granted victim status in the criminal proceedings.
62.  On 10 May 2007 the second applicant complained to the district prosecutor's office about the lack of information concerning the investigation and requested that the investigation be resumed and that she be allowed to study the case file.
63.  On 14 May 2007 the district prosecutor's office partly allowed the second applicant's complaint. Its decision stated that the applicant would receive permission to study the material in the case file “which would not divulge investigative secrets”.
64.  On 16 May 2007 the district prosecutor's office granted the first applicant victim status in criminal case no. 61144.
65.  On 5 July 2007 the district prosecutor's office conducted a crime scene examination at the applicants' household. No evidence was collected from the scene.
66.  On 5 July 2007 and 17 July 2007 the first applicant requested the district prosecutor's office that he be granted the status of a civil plaintiff in the criminal case. No response was given to these requests.
67.  On 20 July 2007 the applicants' lawyer Mr M.A. submitted to the SRJI a written statement concerning his study of the investigation file in case no. 61144. In this letter he described the following:
“... the criminal case file comprises one volume. The case was opened on 30 October 2002 ... Makka Dolsayeva was granted victim status and questioned. Kursolt Dolsayev was also questioned. No other investigative measures were taken. The investigation forwarded information requests to law-enforcement agencies in Chechnya asking whether the latter had apprehended the Dolsayev brothers; according to the responses, the brothers had not been apprehended [by the law-enforcement agencies].
On 30 December 2002 [the prosecutor's office] decided to suspend the investigation owing to the failure to identify the perpetrators; the investigator's decision stated that all possible investigative measures in the absence of anyone to be charged with the crime had been taken.
... the crime scene examination was not conducted. Therefore it is possible to conclude that from the very beginning the investigation in the criminal case led to a dead-end; one could not possibly talk about its effectiveness.
For instance, in their witness statements Kursolt and Makka Dolsayev stated that after the abduction they had seen tyre marks of military vehicles on the ground; however, the investigation did not find that it was necessary to examine the crime scene [although] traces of the criminals or any other evidence left [by the culprits] could have been discovered there ...
The investigation did not question all the witnesses to the crime. [The applicants'] neighbours were questioned only in August 2003.
... on 20 April 2003 the investigation in the criminal case was resumed owing to 'the lack of response to several information requests forwarded to law-enforcement agencies in Chechnya'.
... on 20 May 2003 the decision to suspend the criminal investigation was taken.
On 6 August 2003 the investigation was resumed.
A plan of operational-investigative measures was drawn up on 6 August 2003. According to the prosecutor's office, the investigation's main theory was the abduction of the Dolsayev brothers by servicemen of federal forces. To verify this theory, [the investigation] issued the order 'to conduct by 18 August 2003 an expert evaluation of the objects collected from the crime scene'. However, it should be recalled that the crime scene examination had not been conducted and, consequently, no objects had been collected from the scene. The investigative orders listed in the plan of operational-investigative measures had not been carried out.
The investigation in the criminal case was suspended on 6 September 2003.
On 4 April 2005 the investigation was resumed.
Orders concerning 'verification of the operations conducted by the servicemen of the Urus-Martan FSB and servicemen of the Urus-Martan district military commander's office on the day of abduction' were issued ...
On 4 May 2005 the investigation in the criminal case was suspended.
On 6 June 2005 the investigation was resumed ...
On 6 July 2005 the investigation was suspended.
On 27 November 2006 the investigation was resumed ...
On 28 November 2006 the investigation was suspended.
On 14 May 2007 the investigation was resumed ...
On 18 May 2007 the investigation was suspended again.
On 29 June 2007 the investigation was resumed.
On 5 July 2007 the investigation conducted a crime scene examination, during which photos of the Dolsayev family's household were taken. 'Nothing was collected from the crime scene.'
The investigation file contains the response of military unit no. 6845 to an information request by the prosecutor's office: 'the military commander's office of the Internal Troops [of the Ministry of the Interior] has been stationed in the Urus-Martan district since 2003. At present it is not possible to provide information concerning the military units and their servicemen [stationed in the area in 2002] as in 2002 the military commander's office consisted of units of the Ministry of Defence. [However,] in 2003 the office was discontinued; therefore, it is not possible to provide information as to which units became its successor.'
[In the investigation file] there is also the response of the OG VOGO (operational unit of the temporary operational group – оперативная группировка временной оперативной группы) and PMVD (units of the Ministry of the Interior) (подразделений МВД): 'there is no information concerning the passage of military vehicles through the checkpoints in the Urus-Martan district in the end of 2002 as there is no archive.'
In conclusion, it is possible to say that the investigation of this criminal case has not been carried out. The investigation file contains practically no information other than requests for information and assistance and responses to them; the latter state that none of the law-enforcement agencies in Chechnya apprehended the Dolsayev brothers. The prosecutor's office did not even try to verify whether this was true. The crime scene examination was not conducted until five years after the abduction ...”
(b)  Court proceedings initiated by the applicants
68.  On 31 October 2003 the Urus-Martan District Court of Chechnya (“the District Court”) granted a request by the second applicant and declared Beslan Dolsayev a missing person as of 21 October 2002.
69.  On 17 November 2003 the District Court delivered a similar decision in respect of Rizvan, Rizavdi and Shuddi Dolsayev and declared them missing persons as of 21 October 2002.
70.  On 31 January 2005 the District Court granted a request by the first applicant and declared Beslan Dolsayev deceased as of 21 October 2002.
71.  On 30 October 2002 the district prosecutor's office instituted an investigation into Beslan, Rizvan, Rizavdi and Shuddi Dolsayev's abduction under Article 126 § 2 of the Russian Criminal Code (aggravated kidnapping). The case file was assigned no. 61144. The criminal case was opened within the time-frame prescribed by Articles 143 and 145 of the Code of Criminal Procedure (decisions taken upon receipt of information about a crime) – that is, within ten days from the receipt of the information about the abduction of the applicants' relatives.
72.  The first applicant was questioned on 2 November 2002; the second applicant was questioned on the same date. The second applicant was granted victim status on 30 December 2002; the first applicant was granted this status on 16 May 2007.
73.  The investigation questioned a number of witnesses. On 2 November 2002 the second applicant testified that at about 4 a.m. on 21 October 2002 she had heard some noise from the street. She looked out from the window and saw a group of 20-25 armed men in camouflage uniform and masks. Some of these men entered her house. One of them told her that they were from the GRU. The men put four of the applicant's sons against the wall and asked who was working in the police. Beslan Dolsayev told them that he worked at the Zavodskoy ROVD. Then the intruders took away his service gun, ammunition, service uniform and identity card. After that the men took the applicant's sons outside. They locked her husband Kursolt Dolsayev and her sick son Shamil in a bedroom; the applicant and her daughter-in-law had been locked in another room. After the intruders left, the applicant saw on the ground tyre marks from a car and an APC. On 2 November 2002 the first applicant provided a similar witness statement. However, he also stated that one of the intruders had had a gun with a telescopic sight, and that he had been locked by the intruders in one of the rooms together with his son Adam. On 16 May 2007 the first applicant changed his previous testimony by stating that he had been locked in one of the bedrooms with his son Shamil. On an unspecified date the investigation questioned the fourth applicant, Shamil Dolsayev, whose description of the events was similar to that of his parents.
74.  According to the Government, the applicants provided contradictory statements concerning the subsequent discovery of the knife: the second applicant testified that she had seen the soldier with the knife about a week after the abduction and that the soldier had been accompanied by other servicemen, whereas the first applicant submitted that he had seen the soldier a month after the abduction and that the soldier had been alone. In addition, the applicants' statements contained discrepancies as to the way the soldier had escaped from the applicants. The applicants had also failed to describe the knife's features to the investigation and to inform the authorities that the abductors had stolen their property.
75.  The investigators questioned the applicants' neighbours Ms Kh.N., Mr A.S. and Mr S.A., who had provided similar statements to the effect that they had discovered about the abduction of the Dolsayev brothers from the applicants. The investigators also questioned officer P.M., the head of the road-patrol unit of the Urus-Martan ROVD. According to his statement, he had been informed about the abduction on 21 October 2002. Another witness, the head of the Martan-Chu village administration, Mr E.M., testified that on 21 October 2002 one of the village residents had told him about the abduction of the Dolsayev brothers by unidentified men.
76.  The investigators also requested information about the disappearance of the Dolsayev brothers from various State authorities. On 15 January 2003 the information centre of the Ministry of the Interior stated that it had no records concerning either the detention of the Dolsayev brothers or the opening of criminal proceedings against them. The investigators also obtained information from the public prosecutors' offices and units of the Ministry of Defence, according to which the bodies of the Dolsayev brothers had not been found among the unidentified corpses discovered in Chechnya.
77.  The Government submitted that although the criminal investigation had failed to establish the whereabouts of Beslan, Rizvan, Rizavdi and Shuddi Dolsayev and the internal investigation conducted by the Zavodskoy ROVD into the circumstances of the disappearance of its officer Beslan Dolsayev had also failed to identify those responsible for his abduction, the investigating authorities had forwarded information requests to competent State agencies and had taken other steps to solve the abduction. The investigation found no evidence to support the theory of the involvement of Russian federal forces in the abduction of the Dolsayev brothers. The law-enforcement agencies in Chechnya had never arrested or detained Beslan, Rizvan, Rizavdi and Shuddi Dolsayev on criminal or administrative charges and had not carried out any criminal investigations in respect of them. No special operations had been carried out in the Urus-Martan district on 21 October 2002. In addition, according to the statement provided by the head of the Martan-Chu village administration, at the material time it had been possible to drive in and from the village without passing through the military checkpoints by countryside roads located near Urus-Martan and the villages Tangi-Chu and Goy-Chu (also known as Komsomolskoye).
78.  The Government further submitted that the description of the perpetrators provided by the witnesses did not demonstrate that the perpetrators were representatives of the State. Although the camouflage uniform used by the perpetrators was similar to the uniform of military servicemen, such uniform was available for purchase everywhere in the Russian Federation. In addition, the masks used by the perpetrators did not have individual features distinguishing criminals from military servicemen. The fact that the perpetrators had spoken Russian did not mean that these men must have been Russian military servicemen; they could have been residents of Chechnya or members of illegal armed groups from other countries who spoke the language.
79.  According to the Government, the investigation had been suspended and resumed on several occasions; in spite of the large volume of operational-search and investigative measures carried out by the authorities, the investigation had failed to identify those responsible for the abduction of the Dolsayev brothers. The Government further submitted that at the material time a counterterrorist operation had been taking place in Chechnya and there had been daily attacks on the federal forces. Therefore, owing to the risk this investigative measure could have represented for law-enforcement officers, the prosecutor's office had not conducted the crime scene examination in the applicants' house and its surroundings. The Government further contended that the applicants had been duly informed of all decisions taken during the investigation, that the first and second applicants had been granted victim status in the criminal case and that the investigators had complied with all the instructions issued by the supervising prosecutors.
80.  Despite specific requests by the Court, the Government did not disclose most of the contents of the investigation file in case no. 61144, providing only copies of the following documents:
(a) the second applicant's witness statements, dated 2 November 2002 and 14 August 2003; and
(b) the first applicant's witness statements, dated 2 November 2002, 6 April 2005, 16 June 2005 and 16 May 2007.
The Government stated that the investigation was in progress and that disclosure of the documents would be in violation of Article 161 of the Code of Criminal Procedure, since the file contained information of a military nature and personal data concerning the witnesses or other participants in the criminal proceedings.
